The development of ethology as a scientific discipline has allowed the development of practices that help improve the human-cat relationship and animal welfare. It is for this reason that the new trends in the handling of domestic cats lie in promoting empathy in the respectful handling of domestic cats and the generation of positive experiences when going to the vet, thus avoiding the generation of stress or anxiety. Therefore, a study is proposed to analyze the efficacy of green tea (Camellia sinensis) essential oil as aromatherapy in reducing stress in consulting cats. The proposed study was carried out at the Pet's Home Veterinary Clinic, which is in the Tungurahua Province of the Ambato Canton. The reference population consisted of 45 domestic cats. The sample selection was divided into 3 experimental groups, each of 15 cats that were in healthy conditions with aromatherapy exposure to different concentrations of green tea (5%, 10% and 15%). The experiment model applied to validate the hypothesis responds to the name of Complete experimental design by means of Fisher's test. In conclusion, I have to assert that; green tea as aromatherapy has a relaxing effect in cats based on the p value (0.000 where p value < 0.05) due to the significant behavioral changes between the results of its application.
Efecto antimicrobiano y cicatrizante de los extractos de llantén (Plantago major L.) y manzanilla (Matricaria chamomilla L.) en orquiectomía en cerdos

Bacterial resistance, less adverse effects and economic cost redirect the search for natural therapies. In this research the objective was to compare the antimicrobial and healing effect of plantain (Plantago major L.) and chamomile (Matricaria chamomilla L.) extracts on surgical wounds from orchiectomy in pigs. Plant extracts were obtained by evaporating the solvent. Three treatments were used, the first group (T1) was treated with plantain extract, the second group (T2) with chamomile extract and the control group (T3) with topical gentamicin. The healing process was assessed by means of the PUSH and OSAS scales, while the microbial load was evaluated by means of the CFU/cm2 count. Statistical tests such as Kruskall Wallis, Tukey at 5% and Pearson Chi-square were used for data analysis. The bacteria identified in the orchiectomy wounds were Staphylococcus spp. and Bacillus spp. The parameters evaluated on the PUSH scale determine numerically that the use of T1 is favorable in the healing process and statistically not significant with T1, T2 and T3. While the surface area and flexibility assessed on the OSAS scale improve significantly with the use of T1 in the healing process. Regarding the antimicrobial effect, the use of T1, T2 and T3 reduced the bacterial load from 151 200 CFU/ cm2 to 72 450 CFU/ cm2. Statistically, it is not significant; however, with the use of T1 the reduction is less, going from 166 950 CFU/ cm2 to 73 500 CFU/ cm2
Evaluación del comportamiento del cilantro (Coriandrum sativum) bajo diferentes niveles de nitrógeno en el cantón Colta, provincia de Chimborazo

Coriander is a crop of economic importance for its culinary and pharmaceutical uses; however, its productivity can be affected by both weather variations and deficiencies in fertilization plans. In the present investigation, the effect of the nitrogen fertilization dose on the yield and quality of the coriander (Coriandrum sativum L.) crop was evaluated in Canton Colta, province of Chimborazo, using three sources of nitrogenous fertilizers (urea, ammonium nitrate and Ferthigue) were used at three doses levels (high, medium and low) on the parameters plant height, number of petioles, root length, fresh weight of the plant, time to harvest and yield in purple coriander plants. The experiment was conducted under a split plot design. As results, an interaction effect was found between the source and the dose of the fertilizer applied on the growth of coriander plant measured at 57, 70 and 90 days after sowing. In a similar way, an interaction effect between the source and fertilization dose on the fresh weight in coriander plants was detected, while only the individual effect of the fertilization source in root length and petiole number was observed. Finally, no effect of either the source or the dose was found on the number of plumules per plant or on the time to harvest. Based on the economic analysis, the highest cost-benefit ratio was achieved with urea and ammonium nitrate in the highest doses, however, given that the organic fertilizer also showed promising results, its inclusion is suggested in order to reduce the negative effect of inorganic fertilizers.
